Title: Improved method and apparatus for refining inorganic fibrous materials
IPC: C03C25/00
Filed: 1954-11-12
Abstract: 758,312. Centrifugal separators. CARBORUNDUM CO. Nov. 12, 1954, No. 32797/54. Classes 23 and 82(2). Inorganic fibrous material containing extraneous non-fibrous material, which has been subjected to a preliminary air separation whereby the coarser extraneous material is removed, is suspended in an aqueous medium and subjected to centrifugal force to separate the remaining extraneous material. The airrefining and wet separation may be performed in one process continuous with the production of the fibres. As shown, Fig. 1, the fibres are produced by extruding molten material into an air blast at 10 and are carried in air-suspension into a chamber 12, wherein the coarser material falls to the bottom of the chamber. The coarserefined fibres are collected on a rotating drum 13 and are opened on a beater 14 which is of the type commonly used in the processing of cotton fibres. The fibres are then placed in aqueous suspension in a tank 16 equipped with agitator paddles and the aqueous suspension is introduced through a pipe 19 into a partcylindrical, part-conical vessel 18 tangentially to the cylindrical portion. By virtue of its tangential admission to the vessel 18, Fig. 2, the suspension is rotated at high velocity, throwing the non-fibrous material against the walls, down which it passes before being removed through a port 23. The refined fibrous material is continuously withdrawn through a pipe 24 extending through the top of the vessel 18, as shown, or extending through the side of the vessel at a level below the inlet pipe 19. The refined fibres are drained and may be filtered or made into paper. The non- fibrous material is either periodically withdrawn from the vessel by removal of a cap 25 or is continuously withdrawn through a conduit. The fibres may be formed by other means such as by discharging a stream of molten material on to one or more high speed rotating discs or spinning surfaces from which it is thrown by centrifugal force. The fibres may be of alumina and silica, asbestos or glass.

Title: Method and apparatus for pre-expansion of synthetic polymeric foams
IPC: B29B7/72
Filed: 1964-08-12
Abstract: <PICT:1073571/C3/1> Synthetic polymeric foams are prepared by mixing liquid and gaseous components under pressure, the exit from the mixing zone being controlled by a fluid pressure controlled diaphragm so that it is opened and shut at the same time as the flow of components to the mixing zone is started and stopped.  In Fig. 1 components enter by passages in cap 30 of mixer 10, the mixture passing by hose 14 to valve 15 which has a core 17 which is positioned between jaws 46 and 47, a tubular diaphragm 18, and a passage 25 to admit control fluid into the space 26.  As the pressure of the control fluid is increased, the tubular diaphragm 18 is pressed closer to core 17 until the valve is closed.  A pneumatic control system is described which permits the simultaneous opening and closing of valve 15 and the inlet valves of mixer 10 as well as the automatic flushing of the whole system with solvent at shutdown. Stirrer 40 is turned by motor 43.  The apparatus may be used for producing successive batches of polyurethane foam and permits the maintainance of a constant head in the mixing chamber.

Title: Improvements in or relating to pawl and ratchet devices particularly for brakes of motor vehicles
IPC: F16H25/20
Filed: 1939-12-22
Abstract: 542,724. Pawl and ratchet mechanism. OHLSON, G. E. Dec. 22, 1939, No. 32806. Convention date, Jan. 2, [Class 80 (iii)] [Also in Group XXXIV] A ratchet and pawl device of the type comprising a screw-threaded ratchet bar so that the pawl may be displaced along the bar by rotating the bar as well as by a sliding action comprises a carrier having a tubular part 5 slidable on the screw-threaded ratchet bar 1 and a tubular guide 6 in which the toothed pawl 2 is slidable. The angle v between the guide and the bar is such that the pawl and carrier are self-locking relatively to the bar as regards movement in the direction of the arrow s. The device is particularly suitable for automatic slack adjusting mechanism for brakes. The Specification as open to inspection under Sect. 91 describes also automatic slack adjusting mechanism for, brakes comprising a pair of pawl devises 10, 12, such as above described adapted to engage the threaded bar 14 which is connected at one end 40 to the brake. The pawl 12 is pivoted at 30 to the forked end of a rod 28 connected to a pedal 26 and a pawl 10 is secured to a rod 16 provided with stops 22, 24 for co-operation with a fixed stop 20. In applying the brake the fall on the rod 28 is transmitted to the bar 14 and the brake by the pawl 12 and the pawl 10 and rod 16 are carried along by the bar 14. If the clearance between the brake shoes and the brake drum is excessive, the stop 22 engages the stop 20 so that the bar 14 slides relatively to the pawl 10. During release, the bar returns the distance determined by re-engagement of the stops 24, 20 and the pawl 12 slides on the bar under the action of the springs 36 until it abuts the pawl 10 as shown. The effective length of the bar and the rod 28 is thus shortened. The pawl 12 has a pin 60 that runs in a slot in the pawl 10. The stop 22 may be clamped to the rod 16 so as to yield under excessive force. Manual adjustment may be effected by rotating the bar 14, the connection 40 between the bar and a rod 38 connected to the brake permitting the rotation. In a modification, the bar 14 and rod 28 operate under pressure instead of in tension and the effective length thereof is lengthened to reduce the brake clearance. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to valve actuating mechanism
Inventor: FRY JEREMY JOSEPH
IPC: F16K31/05
Filed: 1957-10-22
Abstract: 865,565. Valves. ROTORK ENGINEERING CO. Ltd. Oct. 22, 1958 [Oct. 22, 1957], No. 32966/57. Class 135. Valve actuating mechanism comprises a valve actuating spindle 1 on which is slidably mounted a clutch member 8 drivably connected thereto, e.g. by splines, spring means 56 normally urging the member 8 into engagement with a power means, e.g. the worm-wheel 6 driven by a worm 12 connected to a reversible electric motor, means, e.g. the lever 51 loaded by the spring 56, for moving the member 8 into engagement with a manual means such as the hand wheel 3, and retaining means 57 for holding member 8 in engagement with the manual means until operation of the power means causes disengagement to the retaining means whereby the member 8 under the spring 56 re-engages the power means. Normally the forked end 53 of lever 51 forces the sleeve 8 downwards until studs 43 in the worm-wheel 6 engage holes in a flange 44 of the sleeve whereby rotation of the worm-wheel and sleeve rotate an axiallyrestrained nut 7 whereby the non-rotatory screwed spindle 1 rises and opens the valve. When the valve reaches the end of its movement or meets obstruction the increased torque moves the worm shaft 5 axially to operate a limit switch 22 for the motor. On depressing lever 51 dogs 42 on the upper end of sleeve 8 engage dogs 41 on the hand wheel, the sleeve being held in this position by bevelled pawls 57 being forced by springs 65 under the flange 44. Should the electric motor be started the pins 43 displace the pawls so that spring 56 shifts sleeve 8 downwards to re-engage with the worm-wheel 6. In an alternative embodiment spindle 1 is keyed to the member 7 so that the shaft is rotated to operate a rotary valve. Backlash between 7 and 8 enables an impact to be transmitted to the velve stem for initially moving it. A disc 83 driven by the sleeve 8 is geared to a shaft 85 connected to limit switches and an indicator.
